   3) Muda's
Muda is a process that does not add value. Reducing or eliminating Muda is an effective way to
Reducing WIP stock before press operation to balance between p operations
      1) Over Stock
Reducing excess stocks to a minimum level Reducing WIP stock balance between press operations
2) Work in Process in the Workshop
Stocks hide all errors in the system (Defects, space, productivity, flexiblity)

MLT Improvement %35,7
• MLT (Stagnation, Work Conveyance and Info) Improvement by process optimization, process elimination and stock management (Action 1-2-3)
• Saving space by reducing over stocks and CT improvement by using inter-process conveyors. (Action 2.1-2.2-2.3-3)
• Efficiency Improvement by Internal TBP (Action 4)
• Total C/T and Changeover Improvement by process optimization, process elimination (Action 2.1-2.2-2.3-3)
• MOD Improvement by eliminating punching operation and quality wall (Action 2.3-3)
